Specification of Letters Patent.

Patented Feb. 8, 1910.

To all whom it may concern:

Be it knownthat I, ALVIN MARTIN STONE,

citizen of theUnited States, and resident of London, England, haveinvented certain new and useful Improvements in TypelVriting Machines,of which the following is a specification.

My invention relates to paper feeding mechanism for typewritingmachines, and more particularly to what is known as condensed recorddevices.

The main object of my invention is to provide improved means forfacilitating condensed record work.

To the above and other ends, the invention consists in the features ofconstruction,

combinations of devices and arrangements of parts hereinafter describedand particularly pointed out in the claims.

Theinvent-ion is shown as applied to a No. 3 Monarch typewriting machinebut the nature of the invention is such that it may be readily adaptedto other forms of writing machines.

The usual paper feeding equipment of the Monarch machine comprlses mamand auxiliary paper feed rollers extending lengthwise of the platen atthe rear and lower side thereof below the printing line and a pair ofpaper fingers arranged above the printing line at the front and upperside of the platen and adjustable lengthwise of a rod or bar on whichthey are mounted, said bar being detachably secured to the platen framein a fixed relation therewith. Devices are also provided for releasingthe paper feed rollers, said releasing means comprising a hand operatedrock shaft.

In carrying out my invention in the present instance, I employ the usualMonarch paper fingers as terminal paper fingers and arrange them tocooperate with the platen near the ends thereof. Between these terminalpaper fingers are arranged a pair of F supplementary paper fingers,these latter being mounted upon a rod or bar which is journaled onsupports detachably secured to the sides of the platen carrier, thislast mentioned rod or bar being spring controlled and having adjustablysecured near one of its ends a depending releasing device or finger.Behind this finger an upright or armis fixed to the feed roll releaserock shaft, said upright carrying a forwardly projecting arm which isadapted to actuate lease mechanism is operated, thus swinging the inneror supplementary paper fingers away from the platen and rendering theminoperative, without, however, affecting the outer or terminal fingerswhich still remain in operative position. i I

My invention is especially designed to facilitate that kind ofcommercial work commonly called condensed record billing, wherein as thebill is written a duplicate is simultaneously written on the record orsales sheet through an interposed sheet of carbon paper. Preferably theregular or terminal paper fingers are arranged to cooperate only withthe record sheet (or in some cases with both the record sheet and thecarbon sheet) while the supplementary paper fingers cooperate with thebill sheet, which is narrower than the record sheet, said bill sheet atno time being under the control of the terminal paper fingers. When myimprovements are made use of and the feed roller releasing mechanism isoperated the supplementary paper fingers are automatically swung toinoperative position and locked in such position so that the bill sheetand carbon sheet (or in some cases the bill sheet only) may be readilywithdrawn from the machine after the bill has been written, withoutdisturbing the record sheet which is held by and remains under thecontrol of the terminal or regular paper fingers. A fresh bill sheet andcarbon sheet may be inserted and ushed around the platen until it is inpositlon for writing the first line, whereupon the feed roller releasingmechanism may be unlocked and the feed rollers and supplementary paperfingers rendered again operative to cooperate with the fresh bill sheet.Thereafter during the usual line spacing movements of the platen thebill and carbon sheets and the record sheet will be fed together throughthe machine and the items of the new bill will be reproduced on therecord sheet close to the last item of the reproduction of theimmediately preceding bill. This is a brief outline of the preferredmethod of using my improvements but it is, of course, to be understoodthat the invention may be used in other ways, and that its novelprinciples may be embodied in other forms of mechanism.

In the accompanying drawings, Figure 1 is a fragmentary full-sized frontelevation of the carriage of a No. 3 Monarch typewriting machineembodying my invention. Fig. 2 is an enlarged fragmentary end view,partly in section, of the platen carrier and mounting, and showing myinvention in combination therewith. Fig. 3 is an enlarged diagrammaticend view corresponding with Fig. 2. Fig. 4 is a diagrammatic end viewlike Fig. 3 but showing certain of the parts in different relations fromthose in which they appear in said Fig. 3. Fig. 5 is a diagrammatic endview showing certain of the parts in still different relations fromthose in which they appear in Figs. 3 and 4. Fig. 6 is an enlargedfragmentary end view looked at from the left and show well as the fingerpiece with which said detent directly cooperates.

In the drawings, 1 indicates the top plate of the machine and 2 brackets(only one of;

which is shown) fixed on the top plate, said brackets having oppositelygrooved trackways 3 secured to them by screws 4. Antifriction balls 5cooperate with the grooved track-ways and with oppositely grooved waysin a rear or slide bar 6 of a platen frame or carrier, said platencarrier comprising also end or side bars 7 extending horizontallyforward from the ends of said slide bar. A rotary platen 8 is journaledin the side bars 7 and is operatively connected at its left-hand endwith a line space ratchet wheel 9 which is adapted to be operated by theusual or suitable line space actuating devices for turning the ratchetwheel and platen in line spacing direction. In addition to the linespace actuating devices referred to, it will be understood that theusual detent (not shown) is provided, said detent cooperating with theline space ratchet wheel 9 toprevent overthrow of the platen in theturning movements thereof and to prevent accidental displacement of theplaten from the line space positions to which it may be successivelyturned; and furthermore that the usual finger wheels are pro-,

vided at the ends of the platen shaft.

Pivoted at 10 in lugs 11 projecting forwardly from the rear bar 6 (seeFig. 2) are downwardly and forwardly projecting arms 12 in which ismounted a shaft 13 carrying the main feed roller 14, said rollercompris- Fig. 8 is an ing one or more sections. Pivoted at 15 in thelower end portions of the arms 12 are small wheels 16 which are adaptedto cooperate with arms 17 pivoted at 18 in the lugs 11, said arms 17 attheir forward end portions carrying a feed roller shaft 19 on which ismounted one or more auxiliary feed rollers 20. Springs 21, secured tothe hanger arms 12, cooperate with fixed abutments 22 on the lugs 11 tomaintain the feed roller 14 normally in cooperative relation or contactwith the platen, while springs 23 secured to the hanger arms 17 tend tomaintain the feed rollers 20 in cooperative relation or contact with theplaten. The feed rollers protrude through openings in a paper apron 24which extends from side to side of the machine beneath and at the rearof the platen and at its ends is coiled or hooked around a shaft 25journaled in the side bars of the carriage. The connections of saidpaper' apron with said shaft are omitted from the drawings for the sakeof clearness, but it will be understood that the paper apron 24 ispivotally connected with the shaft 25. Flat springs 26 secured on thehanger arms 17 cooperate with the paper apron to maintain it normallyclose to the platen, as shown in Figs. 2 and 3 The paper feeding,guiding and controlling devices thus far described are substantially thesame as the corresponding parts of the Monarch machine, and it is deemedunnecessary to here describe them in greater detail. Said paper feeding,guiding and controlling devices may be moved away from the platen, orreleased as it is called, and thereby rendered inoperative by anysuitable means, such as that shown in the drawings.

Projecting from the shaft 25 above each hanger arm 12 are lugs 27 andfixed to and projecting upwardly and forwardly at right angles from eachof said hanger arms. is a lug or pin 28 with which the associate lug 27is adapted to cooperate. The left-hand end of the shaft 25 projectsbeyond the lefthand side bar 7 and has fixed to it by a headed screw 29(Fig. 6) a finger piece or lever 30, the upper end portion of which isbent or twisted at right angles and the rear edge of which, a shortdistance above the screw 29, normally contacts with a stop pin 31 fixedto and projecting laterally from the side bar 7. A lug 32, extendingrearwardly and upwardly from the lower portion of the release lever 30,is adapted to contact with the stop pin 31 when the release lever ispulled forwardly to limit the forward motion of said lever and preventexcess movement of the parts. When the release lever is pulled forwardlyit operates to turn the rock shaft 25 and causes thelugs 27 thereon tocooperate with the lugs 28 on the hanger arms 12 to push said arms 12downwardly and rearwardly about their pivots 10 and result that thepaper apron 24 is relieved of the pressure of said springs and swingsdownwardly about the shaft 25 as a center and away from the platen tothe position shown in Fig. 4.

Itis preferable to lock the paper feed rollers and the paper apron awayfrom the platen in the positions shown in Fig. 4 in order that theoperator may have bothhands free for adjusting the work sheets, and forthis purpose any suitable locking or detaining means may be employed,that shown in the drawings comprising a horizontally disposed spring arm33secured at its forward end to the platen frame in a manner presentlyto be described and having at its free or rear end a pin or stop 33having a beveled face, as clearly shown in Fig. 8. Then the releaselever 30? is. pulled forward its upper portion cooperates with thebeveled face of the in 33 to push the pin out of the way, ben ing orflexing the arm 33 rightward.

After said lever 30 has been pulled forwardly past the pin 33 the latterwill spring back to normal position and will lock the release lever 30forwardly in the position shown by dotted lines in Fig. 8 and by thefull lines in Fig.4. WVhen the release lever is locked in its @forwardposition the feed rollers 14 and 20 will be inoperative as shown in Fig.4.

The detent device or lock for the release lever above briefly describedis the invention ofThomas J. C00 and forms in art the subject-matter ofhis pending app ica tion, Serial No. 345,511, filed November 28, 1906.Said detent device is not therefore claimed herein per se.

The paper feeding devices thus far described, comprising the main andauxiliary paper feed rollers, are adapted to cooperate with the worksheets below the writing line and at the rear and lower side of theplaten. When said paper feed devices are released and locked out ofoperation, as just explained, bothihands of the operator are free toadjust the paper or work sheet to remove it or enter a new work sheet inthe machine, said work sheet, as is well understood, passing down overthe usual paper table 34 (Fig: 2) at the rear of the platen, thence overthe paper apron 24 and between the platen. and the paper feed rollersand between the platen and the usual double employ these paper fingersas terminal paplaten and carriage scale 35, then upwardly at the frontof the platen where it may be guided by suitable paper controllingdevices or paper fingers. These paper fingers may be like the usualMonarch paper fingers, each comprising an off-set guiding portion 36, afeed roll 37 carried by a bifurcated arm 38, and a hanger arm or support39 on which said guiding portion 36 and the bifurcated arm 38 carryingthe feed roll are pivotally supported. These paper fingers are notherein claimed by me per 86 as they are the invention of George A. Seib.The paper guiding portion 36 is provided with a spring 40 tending topress, it constantly toward the platen and the feed roll arm 38 hasseated in it a spring plunger 41 which tends to press the feed roll 37toward the platen. I11 the present instance I prefer to per fingers tocooperate with a comparatively wide work sheet such as a record or salessheet and to permit a narrow sheet, such as a bill sheet to pass betweensaid paper fingers without being touched or controlled by them.

The record sheets sometimes employed are stiff and heavy and in order tobetter control them I prefer to employ an additional spring on eachterminal paper finger to reinforce the spring plunger 41 and increasethe pressure of the feed roll 37 against the platen. The additionalspring is numbered 42 in the drawings and one end of it is connected toa pin 43 extending laterally from the associate hanger arm 39 and theother end to a pin 44 extending laterally from the arm 38 (Figs. 1 and2). When the feed rolls 37 are in cooperative engagement with theplaten, as shown in Fig. 2, the additional springs 42 tend to increasethe pressure of their associate feed rolls 37 against the platen butwhen said feed rolls are thrown off said springs 42 will assist thespring plungers 41 and tend to maintain said feed 110 rolls inoperative,theline of pull of said springs being transferred to the opposite sideof the pivots of the arms 38.

The rear end portion of the hanger arm 39 of each terminal paper'fingeris provided 115 with a laterally extending hub 45 through which passes asupporting rod or bar 46, said rod being secured in lugs 47 extendingupwardly from the side bars 7 of the platen carrier. Headed screws 48cooperate with 120 the supporting rod 46 at its ends and serve to retainsaid rod in fixed relation with the lugs 47 and the platen carrier, saidscrews passing through openings in said lugs 47 and the heads of saidscrews being adapted 12 to abut against the outer faces of said lugs.Between the head of the left-hand screw 48 and the face of the left-handlug 47 the spring detent arm 33 is arranged, it being clamped betweenthe head of the screw 48 1 and the face of the lug 47 as shown in Figs.6 and S. The hanger arms 39have a tongue and groove connection with thesupporting rod 46 so that while the hanger arms 39 may be slid alongsaid rod lengthwise thereof they are held from rotary movement on saidrod.

As has been stated the paper fingers heretofore described are preferablyemployed as terminal paper fingers coiiperating with the platen near itsends and serving to assist in controlling a wide or record work sheet.In addition to these so-called terminal paper fingers I employ a pair ofinner or supplementary paper fingers mounted independently of theterminal paper fingers and arranged between them. The supplementarypaper fingers may be of any desired construction, those shown in thedrawings each comprising a paper guiding portion 49 se-.

cured to a lateral off-set 50 at the lower end of a sheet-meta1 arm 51,said arm being bent into the shape of a U at its upper end portion toprovide bearing portions 52, the latter being formed with key-hole slotsto receive a supporting rod or bar having a spline 54 which is somewhatnarrower than the portions of the keyhole slots with which said splinecoiiperates, as clearly shown in Fig. 2. Arranged on the splined rod 53between the bearing portions 52 of each supplementary paper finger is asleeve 55 (Fig. 1), said sleeve being formed with a key-hole slot whichfits closely on said spline d rod so that the sleeve 55 has no motion ofrotation on said rod, although it may be slid freely along said rod.Fixed to the outer end portion of each sleeve 55 and abutting theneighboring bearing portion 52 of the paper finger is a collar 56provided with crown ratchet teeth which cotiperate with correspondingratchet teeth formed on a collar 57 which is loosely mounted on thesleeve A coiled spring 58 surrounds each sleeve 55, one end of saidspring being secured in the associate collar 57 and the other endthereof being secured to the bearing portion 52 of the arm 51 of thesupplementary paper fin ger. The supplementary paper finger described isessentially the same in construction as that disclosed in the patent toBurnham 0. Stickney, No. 658,931, dated Octoher 2nd, 1900. At the endportions of the supporting rod or bar 53, the spline 54: is cut awayleaving the rod cylindrical. The right-hand cylindrical portion of therod 53 bears in an opening 59 in a supporting bracket or arm 60detachably secured by a thumb screw 61 to the right-hand side bar 7 ofthe platen carrier (Figs. 1 and 7). Referring especially to Figs. 1 and6, the left-hand cylindrical portion of the rod 53 bears in an angularsupporting bracket or arm 62 which is detachably secured to a hanger arm63, the latter being fixedly secured to the rod or bar 46 and curvingfonwardly therefrom as shown in Fig. 6. The hanger arm 63 resembles thehanger arms 39 of the terminal paper fingers and preferably has a smalltongue-and-groove connection with the supporting rod L6, but isprevented from moving endwise of said rod by any suitable means.Extending laterally from the left-hand end portion of the hanger arm 63is a dowel or pin 64, the

lower end portion of the supporting bracket 62 being provided with anopening which fits over the dowel. Said supporting bracket 62 is furthersecured to the hanger arm 63 by a thumb screw 65. The arrangement issuch that while the hangerarm 62 may be readily detached, it is, whenproperly adjusted, maintained in a fixed relation with the hanger arm 63and through the latter with the platen carrier. A coiled spring 66 hasits lower end secured to a pin 67 projecting from the lower end portionof the hanger arm 63, the upper end of said spring being secured to apin 68 fixed to the rod 53. The rod 53 is held from endwise movement bythe cotiperation between the ends of the spline 54: with the inner facesof the supporting brackets 62 and 60, but said rod may turn or rotate inits bearings in said brackets, the tendency of' the spring 66 being torotate said rod so that its top will turn forwardly. WVhen the auxiliarypaper fingers are in operative contact with the platen, those ends oftheir associate springs 58 which are attached directly to the paperfingers become in effect fixed and the tendency of said springs 58tounwind transmits a rotary motion to the collars 57 and 56 and throughthe latter to the sleeve 55 which in turn transmits the impulse to therod or shaft 53 with which it is closely connected. Consequently it willbe seen the paper finger springs 58 tend to turn the rod or shaft 53 oneway while the spring 66 tends to turn said rod the other way. The twocollars 56 and 57 afford a ready means of regulating the tension of theassociate spring 58.

Referring now to the means shown for automatically rendering thesupplementary paper fingers inoperative when the paper feed rollerreleasing devices are actuated, said means comprises a releasing memberor finger 69 adjustably secured to the righthand end portion of the rod53 (Figs. 1, 3, 4 and 5). The lower portion 69 of the release member isflat and thin and the upper portion is thickened and is split asindicated at 70, the lower end of the split 7 Orunning into acylindrical opening through which the rod or shaft 53 passes. A headedscrew 71 connects the split portionsof the finger 69 and when tightenedholds said finger in a fixed relation with the rod 53. By loosening thescrew 71 the finger 69 may be adjusted both lengthwise of the rod 53 andcircumferentially thereof. Coiiperative with the rear" face of the part69 of the releasing finger isfla normally horizontally disposed arm 72,the front end whereof is adapted to contact with the part 69 while therear end which is provided with a hole through which the release rockshaft passes. A set screw 77 serves tosecure the block 76 and the arm 75in. fixed relation with saidrock shaft 25.

This relation may be varied by loosening the set screw so as to enablethe block 76 and rod 75to be turned on said rock shaft 25 or movedlongitudinally thereof to desiredpo sition. The arm 7 2 may be adjustedon the arm 75by loosening the screw 74 so as to enablethe collar 73 tobe slid up and down on the arm 75 to vary the extent of rotationimparted by the arms 72 and 69 to the shaft 52. It will be understoodthat when the release lever 30 is pulled forward, turning the rock shaft25, the arm 75 will be: rocked forward, carrying with it the arm 72 andcausing the front end of the latter to push against the dependingportion 69* of the releasing finger, swinging the latter forwardly andturning the rock shaft 53 until the spline on the latter contacts withthe keyhole slots in the bearing portions 52 of the supplementary paperfingers and then moving said paper fingers automatically out ofoperative position or from the position illustrated in Figs. 2 and 3 tothat in Fig. 4. The arm 72 acts as a stop to limit the rotation of theshaft 53 under the impulse of the spring 66, and said spring and stopnor mally hold said shaft in a fixed position as far as rotation isconcerned. The parts are so adjusted that when the finger 69 is in itsnormal position against the rod 72 and'the paper fingers are against theplaten, the rib 54: of the shaft 53. occupies an intermediate positionin the key-hole slots in the bearing portions 52 of the supplementarypaper fingers, as shown in Fig. 2, said rib or spline not being incontact with either the upper or the lower walls of said slots. Thisinsures that the springs 58 may press the paper fingers against theplaten and affords a slight motion of said paper fingers away from theplaten without turning the shaft 53. It will be apparent that themounting of the paper finger rod or shaft 53 and the mode of connectingthe paper fingers there .with are such that the paper finger springsmight be increased in tension to such an extent by the introduction of aplurality or pile of sheets of paper to the platen that the rod or shaft53 would be rocked and would act on the spring 66 in such a way as tospring 66. The rod or shaft 53 provides in fact an anchorage for one endof each ofthe springs 58, the position of which anchorage may beautomatically varied as varying thicknesses of paper pass under thepaper fingers, thus automatically relieving to some sheet may freelypass. This space is preferably long enough to receive a bill or recordsheet, but as shown in Fig. l, the upper edge of the scale plate 35 isnot cut away near the end portions thereof so that the upper edge of theend portions of said scale may coiiperate with the record or wider sheetoutside the side edges of the narrow bill sheet. lVith the scale plate35 cutaway as shown, it will be apparent from a. consideration of Fig.4: that when the release lever 30 is pulled forward and looked, all ofthe paper feeding devices which coiiperate with the bill sheet arerendered inoperative and locked in inoperative position so that the billsheet may be moved freely around the platen for adjustment or may bewithdrawn readily from the machine and a new bill sheet may be inserted.During this operation, as will be apparent from a consideration of Fig.1, the record sheet will be controlled by the terminal paper fingers andwill be held in the position to which it was last adjusted through theline spacing devices.

After what hasbeen said it is not deemed necessary to explain at greatlength the operation of the improvements hereinbefore de scribed. As hasbeen stated, they may be made use of to advantage in that form ofcommercial work known as condensed record billing. The terminal paperfingers are adjusted to coperate properly with the side portions of thewide record sheet as shown in Fig. 1, said record sheet being designatedby the reference character a. The supplementary paper fingers areadjusted lengthwise of the rod 53 so as to cotiperate properly with theside portions of the bill sheet designated by the reference character b.In some forms of work the interposed carbon sheet or inlay is of thesame width as the record sheet a and is adapted to be controlled by theterminal paper fingers and to remain in the machine as long as therecord sheet does, or until the latter has been completely filled. Inother cases the interposed carbon sheet is only as wide as the billsheet and is introduced into the machine and removed therefrom with saidbill sheet, being controlled bythe supplementary paper fingers, but notby the terminal paper fingers. The

narrower width of carbon sheets is made use of in those forms of workwherein certain entries are made on the record sheet which are notrequired on the bill sheet, as, for example, in some forms of way-billswhere such entries as those coming. under the heads destination, numberof packages, description, weights, rates are duplicated and otherentries such as those coming under the head of paid on, folio, cartage,underoharge, overcharge, ledger, etc. are to be written only on therecord sheet and outside of the field of and to the right of theoverlying carbon sheet. In eithercase the record sheet is introducedinto the machine and fed around with the platen in the usual way untilit is positioned for writing the first line. Thereafter the feed rollrelease lever may be pulled forward and locked, enabling the bill sheetto be introduced either at the front or rear as is most convenient, andpassed around the platen under the supplementary paper fingers untilsaid bill sheet is also positioned for writing the first line. Thereuponthe release lever may be freed from the detent device or lock,permitting the various paper feeding devices which were locked out ofoperation to return to operative positions. The items on the bill maythen be written in the usual way, said items being reproduced throughthe interposed carbon sheet on the record sheet and thereafter therelease lever may be operated to free the main and supplementary feedrollers and at the same time that said feed rollers are released toautomatically release the supplementary paperfingers and lock them out,enabling the written bill to be withdrawn and a new bill sheet to beintroduced without disturbing the record sheet a which at all timesremains under the ,control of the terminal paper fingers. If there isconsiderable writing to be done on the bill sheet so that when thelatter is completed its lower edge has been fed forwardly so far that ithas passed out of the control of the main and auxiliary paper feedrollers, then the operator instead of operating the release lever 30 maymerely grasp the lower end of the portion 69 of the releasing finger 69and pull the latter forwardly, thereby rendering the supplementary paperfingers inoperative and enabling the bill sheet to be withdrawn withoutaffecting either the paper feed rollers or the rock shaft 25 and theautomatic releasing devices carried thereby, including the arms 7 5 and72. This op eration will be understood from a consideration of Fig. 5,wherein the releasing finger 69 is shown pulled away from the arm 72,effecting a release of the supplementary paper fingers withoutdisturbing said arm 7 2 or the parts connected therewith. From what hasbeen said it will be apparent that the releasing finger performs adouble function, not only cooperating with the arms 7 2 to automaticallyrelease the supplementary paper fingers but also serving as a fingerpiece to enable a manual release of said supplementary paper fingers tobe effected vention.
